[0:37] <methuzla> julius_: ~100mA
[0:39] <julius_> thanks
[0:39] <methuzla> julius_: http://raspi.tv/2017/how-much-power-does-pi-zero-w-use
[0:39] <julius_> ah great
[0:40] <julius_> was just curious if battery operation for a camera that gets activated when movement is detected via a pir sensor
[0:40] <julius_> would be possible
[0:41] <julius_> but with 100ma, one would need a big battery
[0:41] <methuzla> wildlife camera?

[0:47] <julius_> whats a wildlife camera?
[0:48] <julius_> found a pi zero on aliexpress with a 5mp camera module connected via the flat "ribbon" cable

[0:53] <swift110> nice julius_
[0:55] * jaziz (~jaziz@unaffiliated/jaziz) Quit (Ping timeout: 268 seconds)
[0:55] <methuzla> julius_: camera that takes photo of animals (wildlife) when they walk by
[0:55] <methuzla> julius_: how long do you want camera to run?
[0:55] <julius_> ah ok...
[0:55] <swift110> methuzla: I want to build one of those
[0:55] <julius_> at least 10minutes
[0:56] <methuzla> in total? thats very doable with battery. can go up to hours.
[0:56] <julius_> kind of a burglary alarm, send out intrusion detection message via wlan and also record a few minutes
[0:57] <julius_> sure, but how long can a bettery last when the zero uses its ~60ma idle all the time
[0:57] <methuzla> hours
[0:57] * whatever_hi (~whatever_@63-157-105-234.dia.static.qwest.net) Quit (Remote host closed the connection)
[0:57] <julius_> was more thinking about weeks....gonna go with a 5v power supply
[0:58] * plugwash (~plugwash@2a02:c7f:ba49:1500::2) has joined #raspberrypi
[0:58] <julius_> is it allowed to ask orange pi questions here?
[0:58] <swift110> wow
[0:58] <methuzla> meh. not disallowed. but don't expect answer.
[0:59] <methuzla> and weeks would indeed require a large a battery or some other tricks
[1:00] <dtype> you can get pretty big usb batteries these days
[1:01] <dtype> a moderately large 30Ah one would be 300h at 0.1A idle (about that of a pi0)
[1:01] <dtype> assuming that you get the ideal math out of it
[1:02] <dtype> camera is going to use battery too though, along with motion sensing processing
[1:03] * divx118 (~divx118@5ED66EB7.cm-7-7b.dynamic.ziggo.nl) Quit (Ping timeout: 268 seconds)

[1:05] * kingarmadillo (~kingarmad@host-67-21-184-89.nctv.com) has joined #raspberrypi
[1:06] <julius_> ok, didnt know that
[1:07] <julius_> thats actually almost what i need
[1:07] <mfa298> dtype: except that the Ah rating is likely at 3.7V rather than the 5v needed by the pi, so you might be drawing nearr 0.2A from the battery
[1:07] <mfa298> also a battery claiming 30Ah may well be using alternative facts (i.e. made up numbers)
[1:08] <dtype> yep, and may not provide that at a particular draw
[1:08] * de-facto (~de-facto@gateway/tor-sasl/de-facto) Quit (Ping timeout: 240 seconds)
[1:08] <codingpanic> really, alternative facts?
[1:08] <dtype> but one could shoot for half of ideal/advertised and at least have some place to work from for napkin calculations
[1:08] * codingpanic wished people would stop using that phrase
[1:09] <HrdwrBoB> codingpanic: alternative facts?
[1:09] <HrdwrBoB> it's a great way to say lies
[1:09] * fjrichman (8ae5995b@gateway/web/cgi-irc/kiwiirc.com/ip.138.229.153.91) Quit (Quit: http://www.kiwiirc.com/ - A hand crafted IRC client)
[1:09] <codingpanic> HrdwrBoB: yeah, but it sounds doubleplusungood
[1:10] <HrdwrBoB> heh
[1:10] <codingpanic> they are not facts at all
[1:10] <codingpanic> they are just lies
[1:10] * kingarmadillo (~kingarmad@host-67-21-184-89.nctv.com) Quit (Ping timeout: 256 seconds)
[1:10] <HrdwrBoB> are you saying that people in the governemnt are lying?
[1:10] <codingpanic> HrdwrBoB: this isnt a political channel
[1:11] <HrdwrBoB> I know, I'm also being sarcastic
[1:11] <mfa298> for electronics those made up numbers are often based on something in reality, they're just not useful numbers
[1:11] <dtype> back to the topic, and taking bets on whether or not a 30Ah battery will sustain a little p0 for a week
[1:12] <HrdwrBoB> dtype: the only way to be SURE is to test
[1:12] <HrdwrBoB> because the real world is harsh
[1:12] <dtype> fire one up, let it idle, and let's watch it for a week over a few beers?
[1:12] <julius_> i was thinking about starting the pi zero via a atmega which would look for movement in the room. but from my rpi2 experience i guess boot times of the zero will be to slow
[1:12] * Lorduncan (~Thunderbi@47.62.71.174) Quit (Quit: Lorduncan)
[1:12] <HrdwrBoB> dtype: yep
[1:12] <HrdwrBoB> dtype: live stream too
[1:13] <HrdwrBoB> julius_: way too slow
[1:13] <HrdwrBoB> pi3 with decent storage is reasonably fast
[1:13] <julius_> is there maybe a way to use the pi zero to just record the camera signal without having a full os running in the background?
[1:13] <HrdwrBoB> I don't find it a problem in the car
[1:14] <mfa298> i suspect the average curent draw of a pi zero doing something useful is > 0.1a
[1:14] <julius_> HrdwrBoB, thats where my pi2 will be soon :)
[1:14] <HrdwrBoB> julius_: http://imgur.com/a/quEDa
[1:14] <HrdwrBoB> I just ordered a new 7" 1024x600 touchscreen for it

[1:23] * j08nY (~j08nY@kou-street209-53.pks.muni.cz) Quit (Quit: Leaving)
[1:23] <HrdwrBoB> car radios have lots of features that are hard/impossible to replicate
[1:24] <HrdwrBoB> like adding an FM radio ... I did it with a USB radio, but it pinned the cpu (which I could live with), but it was also about 5 seconds delayed due to the way it worked, which ends up being a dealbreaker
[1:24] <HrdwrBoB> lots of little issues like that
[1:28] * dreamon (~dreamon@unaffiliated/dreamon) Quit (Ping timeout: 268 seconds)
[1:31] <julius_> that is very true
[1:32] <julius_> hard to replicated and you dont come out cheaper

[1:46] <Chillum> mfa298: my experiments showed that while idle with no usb devices it was at about 80mA
[1:47] <Chillum> that was with no GPU usage either though, that GPU will use a fair bit mroe

[1:58] <Duckle|wasDumle> Hey there. I'm trying to cut corners here, and was wondering if the pi would be ok if connected to some IO that is pulled to 5v through a 10k resistor?

[2:06] <Chillum> Duckle|wasDumle: I have done it and it worked
[2:06] <Chillum> but after a few months the pin died
[2:06] <Duckle|wasDumle> 10k?
[2:06] <Duckle|wasDumle> or lower?
[2:06] <Chillum> yes
[2:07] <Duckle|wasDumle> dang. I guess I'll have to make a small board for this level-shifter then
[2:07] <Chillum> I had another, it is still working after ayear

[2:08] <Duckle|wasDumle> It's a pullup for a pfet
[2:08] <Chillum> oh
[2:08] <Duckle|wasDumle> adding a resistor to gnd would kinda defeat the purpose
[2:08] <Duckle|wasDumle> :)
[2:08] <Chillum> ya one of those super cheap level shifter boards will do nicely
[2:08] <Duckle|wasDumle> yea
[2:08] <Duckle|wasDumle> this one just has 4 channels, and I only need 1 :P
[2:08] <precarken> Hello all, just finished my first Raspberry Pi project... Controlling a k'nex roller coaster motor and LED lights... I'm getting ready to add a k'nex ferris wheel, once I add it though I will not have any pins left. What do people normally do when you have used up all pins? https://www.youtube.com/watch?v=_6Pb5WgyIvQ

[2:13] * amigojapan_bnc (Elite19001@gateway/shell/elitebnc/x-fzhcdmfcihxzgkit) has left #raspberrypi
[2:13] <plugwash> Chillum, while it is just one transistor it is a transistor with pretty specific properties
[2:13] <Duckle|wasDumle> It's an nmos, logiclevel
[2:14] <Duckle|wasDumle> not much more specific than that is it?
[2:14] <plugwash> I seem to remember people struggling to find a throuhole part with the right properties
[2:14] <Chillum> no, which phillips doc?
[2:15] <Duckle|wasDumle> Chillum: https://cdn-shop.adafruit.com/datasheets/an97055.pdf
[2:15] <Chillum> a through hole version would be handy

[3:00] <BurtyB> hmoney, :) did the network side of things play OK for you?
[3:01] <hmoney> yeah.. turns out once i installed docker on the controller, then it automatically blocks all network connections to the zero's. I just had to run a simple iptables command and I was back up and running
[3:01] <hmoney> I thought my router was going crazy
[3:01] <hmoney> the zeros would all pop up as connected clients then disappear 5 seconds later
[3:02] <hmoney> I'm now going to try and get someone to 3d print this case for me: https://www.tinkercad.com/things/3ESgqNZjDJJ-clusterhat-case
[3:02] <hmoney> I clicked a link on tinkercad's website and did a price check, they wanted like 45+shipping though :(

[3:07] <BurtyB> hmoney, I hadn't seen that before - looks a bit big for my 3d printer tho as is :/
[3:08] <hmoney> yeah I'm not 100% sure it's necessary, nor worth the money, but I'm still gonna see what the cheapest option is before i build a small box
[3:09] * BurtyB ordered the bits for https://groups.google.com/forum/#!searchin/clusterhat/case$20modmypi%7Csort:relevance/clusterhat/_dVg2heVLw8/McygLGoRAwAJ a while ago tho I haven't put it together yet
[3:10] <hmoney> damn
[3:10] <hmoney> just looks like a storage container with a hole drilled into it lol
[3:13] <BurtyB> heh true - I'm prob going to take off a micro usb connector (or err not put one on) and wire it up to one of the sockets to I don't have the usb cable outside but it should be a bit safer on my super tidy desk in a case ;)

[3:28] <[Saint]> It's the modmypi stacker case with a bunch of additional stacker rings, apparently.
[3:29] <[Saint]> I do have the Pi cluster hat, but due to the fundamental limitations of the Pis themselves I find that clustering with them is pretty foolish.
[3:29] <GreeningGalaxy> too much communication overhead?
[3:30] <[Saint]> Eh, not really. Just piss-poor latency and throughput potential.
[3:30] <[Saint]> I do have a couple of Pi-based clusters, but I use an ODROID XU4 as the client and Rpi 3s as the slaves.

[4:08] <danielmetlitski> hello
[4:08] <Sonny_Jim> Hi
[4:08] <danielmetlitski> i just got a raspberry pi zero w and im having trouble setting it up
[4:08] <Sonny_Jim> ok
[4:09] <danielmetlitski> i got the basic pac that comes with a microUSB with the NOOBS installed
[4:09] <danielmetlitski> and i wanna ssh into my raspberry pi
[4:09] <danielmetlitski> but i cant find a config.txt file on the microusb

[4:12] <Sonny_Jim> I appreciate NOOBS is supposed to help new users, but I think it can cause confusions, such as this

[4:13] <danielmetlitski> and i dont have a monitor
[4:13] <Sonny_Jim> NOOBS doesn't let you see the config.txt (it's held on a partition Windows can't see)
[4:13] <danielmetlitski> so i wanna connect via ssh
[4:13] * de-facto (~de-facto@gateway/tor-sasl/de-facto) has joined #raspberrypi
[4:13] <danielmetlitski> im on mac by the way
[4:13] <Sonny_Jim> So yeah, just download and install Raspbian
[4:13] * alexandre9099 (~alexandre@gateway/tor-sasl/alexandre9099) has joined #raspberrypi
[4:14] <danielmetlitski> onto where
[4:14] <danielmetlitski> the SD card?
[4:14] <Sonny_Jim> Yes
[4:14] <Sonny_Jim> Instructions are available on the wiki (somewhere)
[4:14] <danielmetlitski> err
[4:14] <danielmetlitski> well it should be simple
[4:14] <danielmetlitski> but i dont wanna erase this sd card
[4:14] <danielmetlitski> since it came a long with it
[4:14] <Sonny_Jim> https://www.raspberrypi.org/documentation/installation/installing-images/mac.md
[4:14] * Sonny_Jim shrugs
[4:14] <Sonny_Jim> It's just data
[4:15] <danielmetlitski> why would they disable ssh in noobs
[4:15] <danielmetlitski> wtf
[4:15] <Sonny_Jim> There's a very good reason
[4:15] <danielmetlitski> ?
[4:15] <Sonny_Jim> In fact SSH is disabled in Raspbian too
[4:15] <danielmetlitski> so people without screens cant connect?
[4:15] <Sonny_Jim> Having over a million devices with SSH exposed and a default password is not good
[4:16] <Sonny_Jim> You can turn on SSH easily enough under Raspbian by creating a file called 'ssh'
[4:16] <Sonny_Jim> Not sure about NOOBS
[4:16] <danielmetlitski> hmm
[4:17] <danielmetlitski> also
[4:17] <danielmetlitski> do you know if the raspberry pi zero w has a light
[4:17] <danielmetlitski> that helps you know if its turned on
[4:18] <Sonny_Jim> No idea, I only have the 'normal' ones
[4:18] <Sonny_Jim> The wiki will probably have the answer
[4:19] <Sonny_Jim> "the PI zero does NOT have a power LED, only an activity LED which becomes only active after the PI is booting."

[4:19] <Sonny_Jim> Well, you need to issue a shutdown, but you can't do that headless with no network
[4:19] <danielmetlitski> hmm yes
[4:20] <Sonny_Jim> So yeah, just yank it out. There's no power button
[4:20] <Sonny_Jim> You can always make your own if you see fit
[4:20] <danielmetlitski> is it bad to yank it?
[4:20] <Sonny_Jim> Well, 'carefully remove it' would be better ;)
[4:20] <danielmetlitski> ok
[4:20] <danielmetlitski> im gonna go to the dollar store rite now to see if i can find some cables

[6:30] <redrabbit> pwm regulation noise maybe
[6:31] <Sonny_Jim> Chips generally don't make any noise
[6:31] <Sonny_Jim> It'll be the inductor/transformer, it changes pitch when the load on the PSU changes

[8:18] <danielmetltiski> do you know
[8:18] <danielmetltiski> does it support 5G networks?

[8:50] <danielmetltiski> works
[8:51] <danielmetltiski> via ssh
[8:51] <danielmetltiski> ill try sudo apt-get update i guess
[8:52] <Sonny_Jim> ping google.com
[8:52] <Sonny_Jim> or ping 8.8.8.8 if you just want to check for internet and not DNS resolving
[8:52] <danielmetltiski> pi@raspberrypi:~ $ ping google.com ping: unknown host google.com
[8:52] <Sonny_Jim> Right, so try ping 8.8.8.8
[8:52] <danielmetltiski> pi@raspberrypi:~ $ ping 8.8.8.8 connect: Network is unreachable
[8:52] <Sonny_Jim> There you go
[8:52] <danielmetltiski> ok so
[8:52] <Sonny_Jim> Did you manually configure your internet?
[8:52] <danielmetltiski> error in my conf file?
[8:53] <Sonny_Jim> Sounds like the Pi doesn't know what gateway it's supposed to use
[8:53] <danielmetltiski> i cinfigured it with
[8:53] <danielmetltiski> pi@raspberrypi:~ $ sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
[8:53] <danielmetltiski> and changed the SSD to my network name

[8:53] <Sonny_Jim> So what we can gather, it's connected to your Wifi network, your PC can connect to the Pi via ssh, right?
[8:54] <danielmetltiski> im not sure if its connected to my wifi network
[8:54] <danielmetltiski> since its giving me that error
[8:54] <danielmetltiski> but i can connect to the pi via ssh yes
[8:54] <Sonny_Jim> How is the Pi connected to your home network, via a cable or Wifi
[8:54] <danielmetltiski> via microusb
[8:54] <danielmetltiski> cable
[8:54] <Sonny_Jim> ...
[8:54] <danielmetltiski> oh
[8:55] <danielmetltiski> it should be connected to my network via wifi, sorry

[8:56] <Sonny_Jim> So to connect to your Pi via ssh it's using the Wifi, right?
[8:56] <danielmetltiski> no
[8:56] <danielmetltiski> microusb
[8:56] <danielmetltiski> i think at least
[8:56] <danielmetltiski> i plugged it into my mac with a microusb
[8:57] <Sonny_Jim> Odd
[8:57] <danielmetltiski> same cable as an android phone
[8:57] <Sonny_Jim> Didn't know that you could connect via the microusb
[8:57] <danielmetltiski> its the only way i can connect

[8:58] <Sonny_Jim> So what IP address do you use to connect via ssh?

[9:00] <danielmetltiski> im on mac
[9:00] <danielmetltiski> also im on ubuntu
[9:00] <Sonny_Jim> So what's the ssh command you use to connect
[9:01] <danielmetltiski> sudo ssh pi@raspberrypi.local
[9:01] <Sonny_Jim> Hmm
[9:01] <Sonny_Jim> You don't need to use sudo btw
[9:02] <danielmetltiski> thx
[9:02] <danielmetltiski> but what now
[9:02] <Sonny_Jim> could you ping raspberrypi.local and see what the IP address is please?
[9:02] <Sonny_Jim> (do this on the mac)
[9:02] <danielmetltiski> 64 bytes from 169.254.5.198: icmp_seq=9 ttl=64 time=0.372 ms
[9:03] <Sonny_Jim> Ah ok, it's not getting any DHCP response
[9:03] <Sonny_Jim> On the pi, run 'service dhcpcd status'

[9:09] <Sonny_Jim> Did you enter in the correct ssid?

[9:11] <danielmetltiski> umm
[9:11] <danielmetltiski> is my ssid the same this as my network name
[9:11] <danielmetltiski> i tried two variations of it
[9:11] <Sonny_Jim> Yes

[9:28] <Sonny_Jim> Yeah, you swapped some digits there ;)

[9:32] <Sonny_Jim> If you find you get poor wifi performance, consider moving your wifi channel to something other than 6
[9:32] <danielmetltiski> whatever that means >.<
[9:32] <danielmetltiski> ok cool
[9:32] * Sonny_Jim shrugs
[9:32] <danielmetltiski> ok time to see the desktop
[9:32] <Sonny_Jim> If it works, leave it alone, but it's something to consider
[9:32] <danielmetltiski> vnc
[9:32] <Sonny_Jim> There's apps available for android/iOS that can show you visually which WiFi channels are in use
[9:33] <danielmetltiski> its 1:30 am and i got work at 7
[9:33] <danielmetltiski> screw it i got this far lets keep going :D

[9:36] <danielmetltiski> any clue how to connect to vnc via mac?
[9:36] <danielmetltiski> i did apt-get update
[9:36] <danielmetltiski> and did sudo apt-get install realvnc-vnc-server realvnc-vnc-viewer
[9:37] <danielmetltiski> and i did
[9:37] <danielmetltiski> sudo raspi-config
[9:37] <danielmetltiski> following this guide
[9:37] <danielmetltiski> https://www.raspberrypi.org/documentation/remote-access/vnc/
[9:37] <Sonny_Jim> personally, I use x11vnc, as that will connect to an already running X server
[9:37] <Sonny_Jim> vnc-server creates a 'new' desktop for each VNC session
[9:37] <danielmetltiski> i think mac has some sort of vnc built in>
[9:37] <danielmetltiski> ?
[9:37] <danielmetltiski> not sure
[9:37] <Sonny_Jim> (and is generally more of a pain to get working)
[9:40] <danielmetltiski> ok i downloaded a program called VNC viewer
[9:40] <danielmetltiski> what can i search for
[9:40] <danielmetltiski> 8.8.8.8?
[9:41] <Sonny_Jim> Are you looking for the ip address of the pi?
[9:41] <kerio> Sonny_Jim: he's using g_ether
[9:41] <danielmetltiski> https://www.raspberrypi.org/documentation/remote-access/vnc/
[9:41] <danielmetltiski> YES
[9:41] <kerio> which is incredibly helpful
[9:41] <danielmetltiski> yes* g_ether
[9:42] <Sonny_Jim> kerio: Not anymore ;)
[9:42] <kerio> (because you can enable it just with config.txt and cmdline.txt from the vfat partition)
[9:42] <Sonny_Jim> danielmetltiski: ifconfig wlan0
[9:42] <Sonny_Jim> That will give you the ip address of the wireless card in the zero
[9:42] <kerio> Sonny_Jim: still probably a good idea to leave it enabled, if he doesn't need the usb port for something else
[9:42] <danielmetltiski> https://hastebin.com/hagunuzepo.rb
[9:42] * Sonny_Jim nods
[9:42] <kerio> alternatively, g_serial i guess?
[9:43] <Sonny_Jim> kerio: Confused the heck out of me, as I didn't realise that the Zero had USB networking
[9:43] <kerio> it also works on the pi1 i believe
[9:43] <kerio> it only works on 2 and 3 if you desolder the usb hub
[9:43] <kerio> it's usb gadget mode
[9:43] <danielmetltiski> kerio any clue how to vnc in?
[9:44] <kerio> if the pi supported actual usb otg you could just use an actual cable that's up to spec
[9:44] <kerio> to avoid having to do any sort of configuration
[9:44] <kerio> but alas
[9:44] <kerio> danielmetltiski: do you even have a desktop running?
[9:44] <danielmetltiski> desktop?
[9:44] * Sonny_Jim hands over to kerio and wanders off to listen to some websdr

[9:47] <danielmetltiski> do i need to leave the console ssh connection
[9:47] <kerio> you can just make more than one connection, anyway
[9:48] <danielmetltiski> ok so
[9:48] <danielmetltiski> i enabled vnc now
[9:48] <danielmetltiski> with sudo raspi-config
[9:48] <kerio> it should be the same on macos, btw
[9:48] <kerio> just download the vnc viewer for mac instead of the one for windows

[10:10] <kerio> oh wait, also hdmi_force_hotplug=1
[10:10] <danielmetltiski> omg omg
[10:10] <shiftplusone> Yes, but one doesn't exclude the other. The resolution is automatically detected from the monitor and that's used by VNC as well. Since there is nothing, I think it will default to composite output, which is low res. If you do what kerio said, that should override that.

[12:12] <Shadonovitch> Hey, when you use Pulseaudio networking, is the server the one playing and streaming to client ?
[12:13] <shiftplusone> No, I believe the server is the one actually outputting the audio to the hardware.
[12:13] <shiftplusone> The client streams to the server.
[12:13] <Shadonovitch> In my case, i've managed to connect bluetooth A2DP to the raspberry analogic output ; the next part of my project is to stream this to other pi's within the wifi network
[12:14] <Shadonovitch> So, should the server be on the bluetooth end ? Or on the players end ? I don't really understand all I read about pulse networking
[12:15] <Shadonovitch> "One of PulseAudio's unique features is its ability to stream audio from clients over TCP to a server running the PulseAudio daemon reliably within a LAN" from the man page ;; this means the server is playing the sounds, not the clients, right ?
[12:16] <Shadonovitch> In my case, i'd want clients to connect to the server and play what the server plays'
[12:16] <shiftplusone> I think you might be using 'playing' a little differently here.
[12:16] <Sonny_Jim> Mix it down to an mp3 stream and use something like icecast, would be my suggestion
[12:16] <shiftplusone> By play, I would mean that it is the device that talks to the actual audio device.
[12:16] <shiftplusone> where the speakers would be
[12:16] <shiftplusone> that's the server end
[12:17] <shiftplusone> The server plays the audio. The client sends the audio to be played by the server.

[12:17] <Shadonovitch> shiftplusone: i see what you mean. Although it meeans there's no way i'm doing my project using Pulse then :/
[12:17] <Sonny_Jim> Well
[12:18] <Sonny_Jim> I guess you have a single source, right?
[12:18] <Shadonovitch> Yep'
[12:18] * doomlord (~textual@host86-153-153-151.range86-153.btcentralplus.com) has joined #raspberrypi
[12:18] <Sonny_Jim> And you want that single source to be played out to clients connecting to the server, correct?
[12:18] <HrdwrBoB> sooo
[12:18] <HrdwrBoB> like a stream
[12:18] <Shadonovitch> Exactly, so that it gets play on many different speakers
[12:18] <shiftplusone> it would work, but I would use something like MPD or icecast.
[12:18] <HrdwrBoB> if only that technology existed :P
[12:18] <Sonny_Jim> ^
[12:18] <Sonny_Jim> mpd or icecast will do that for you
[12:19] * sandeepkr (~sandeepkr@ec2-54-255-178-4.ap-southeast-1.compute.amazonaws.com) has joined #raspberrypi
[12:20] <Shadonovitch> I'd need to find a way to turn the A2DP stream to mp3 though
[12:20] <Sonny_Jim> Well
[12:20] <Sonny_Jim> Not to mp3, icecast/mpd will do the encoding for you
[12:20] <Sonny_Jim> I *think* you might even be able to mirror what's playing out the soundcard with mpd/icecast
[12:21] <Sonny_Jim> So as along as the A2DP stream comes out of the speakers, you'll be able to stream it out
[12:21] * mythos (~mythos@unaffiliated/mythos) has joined #raspberrypi
[12:21] <Shadonovitch> Sonny_Jim: my first idea was to hook pulse sink of the audio output to the network one way or the other ;; thanks for the names although, i need to man mpd/icecast
[12:22] <Sonny_Jim> http://icecast.org/ices/docs/ices-2.0.2/inputs.html
[12:22] <Sonny_Jim> I think you'll find a way of doing it there
[12:23] * j4ckcom (~j4ckcom@unaffiliated/j4ckcom) has joined #raspberrypi
[12:23] <Sonny_Jim> If I'm reading it right, then you can use OSS or ALSA as the source input
[12:23] <Sonny_Jim> and IIRC, pulseaudio is just a layer ontop of ALSA anyway
[12:24] <j4ckcom> ABC
[12:25] <Shadonovitch> Sonny_Jim: OpenSound : "This will read audio from the DSP device " -> looks like it
[12:26] <Sonny_Jim> Yeah I certainly believe it's possible
[12:26] <Sonny_Jim> It can be a bit of a configuration nightmare
[12:27] <Sonny_Jim> Might be an idea to setup a simple mp3 streamer first, then try and use the bluetooth/soundcard output as the input source
[12:27] <Shadonovitch> That's what I was after with Pulse yeah
[12:28] <Shadonovitch> Anyway, i'm off for lunch; Thank you for your time :)

[15:34] * feksclaus (~feksclaus@80-71-131-204.u.parknet.dk) has joined #raspberrypi
[15:34] <ScrumpyJack> i'm reading the configfs gadget docs on kernel.org atm
[15:35] <kerio> ScrumpyJack: would it just be a usb serial marked as a known usb hwrng?
[15:35] <ScrumpyJack> kerio: think device proxy
[15:35] <Chillum> ScrumpyJack: you don't want to point devices directly to the hwrng, you want to use something like rngtools to use hwrng as the seed source to fuel the entropy for /dev/random
[15:35] <kerio> no i mean
[15:36] <ScrumpyJack> Chillum: sorry yes, rngtools or other
[15:36] <Chillum> I wonder just how good the hwrng is... I know I have used it to make bitcoin wallets, nothing stolen yet
[15:37] <kerio> Chillum: just pipe it into urandom
[15:38] <Chillum> no, you don't want to access the numbers directly, it is more of an entropy source
[15:38] <Chillum> you want to feed it into your entropy pool then acess it from /dev/random
[15:38] <Chillum> then point your apps to use that instead of urandom
[15:39] <kerio> writing in /dev/random results in exactly that
[15:39] <kerio> and no, use urandom
[15:39] <Chillum> if for some reason urandom stops getting the feed it will just fall back to a poorer system, if random stops getting the feed it will block
[15:39] <Chillum> big difference
[15:39] <kerio> that is not how it works
[15:39] <Chillum> urandom does not block, if just falls back
[15:40] * jkridner (~jkridner@pdpc/supporter/active/jkridner) has joined #raspberrypi
[15:40] <Chillum> random will block when exhausted
[15:40] <kerio> even with linux's idiotic difference between random and urandom, you're still running a csprng
[15:40] <Chillum> yes, but random relies on an entropy pool and will block when that pool is exhausted
[15:40] <kerio> except that "exhausted" is not something that can be estimated correctly in any way and is not something that's in any way meaningful for the entropy pool of a csprng
[15:40] <Chillum> and urandom will just amke stuff up
[15:40] <kerio> "just make stuff up" by running a csprng, yes

[15:42] <Chillum> if you use urandom you don't really know that you are using the hwrng at any given time, say if you ask for random numbers too fast it will overuse the entropy given by the hwrng

[15:42] <Chillum> of course you can overuse entropy
[15:43] <Chillum> that is the whole point of the entropy pool
[15:43] <kerio> that's for reseeding
[15:43] <Chillum> what do you think the seed is?
[15:43] <kerio> so that an attacker has to know all the sources of your entropy all the time to know exactly which numbers are going to be outputted
[15:43] <Chillum> that is the entropy
[15:43] * Lorduncan (~Thunderbi@47.62.71.174) has joined #raspberrypi

[15:43] * p71_ (~chatzilla@75.128.224.180) Quit (Excess Flood)
[15:43] <kerio> and you use them for a csprng
[15:43] <kerio> you're not going to "run out"
[15:44] <Chillum> it is not just about guessing the seed, if you use the same seed for an infinite string of prngs it is more susceptible to pattern analysis, if only theoretical
[15:44] <kerio> "infinite"
[15:45] <Chillum> as the string grows
[15:45] <kerio> yes, you might start getting into problems after 2^128 bits or so
[15:45] <kerio> so that's 3E22 petabytes
[15:45] <Chillum> you know there is a reason why tools like PGP don't use urandom and insist on blocking until enough entropy for random is available
[15:45] <Chillum> it is not just to annoy people
[15:46] <Chillum> the thing about security is that a bit of understanding can be a terrible thing, the devil is in the details

[15:50] * elnormous (~elnormous@gateway.evolutiongaming.com) has joined #raspberrypi
[15:50] <kerio> literally the same data path
[15:50] <Chillum> but random will limit how much it uses a given set of seed data to a finite amount
[15:50] <kerio> random just blocks whenever it feels like it hasn't been fed enough entropy
[15:50] <kerio> which is stupid
[15:50] <kerio> and urandom will never block, even if it hasn't been initialized at all
[15:50] <kerio> which is VERY stupid
[15:50] <Chillum> it is not stupid, these prng algos are not perfect you realize
[15:51] <Chillum> would you make up on really good random seed then use it for the rest of your life?

[15:51] <kerio> https://security.stackexchange.com/questions/3936/is-a-rand-from-dev-urandom-secure-for-a-login-key/3939#3939
[15:52] <kerio> and those two aren't just random hacks, mind you
[15:53] <Chillum> urandom provides very good numbers, but people who use a HWRNG sort of want those hardware rngs to actually be used
[15:53] <Chillum> random makes sure it is being used
[15:53] <Chillum> urandom does not
[15:53] <kerio> yes, which is why you use them to constantly feed the csprng state
[15:53] <Chillum> and you have no way of knowing if it is
[15:53] <kerio> and you'd be wrong
[15:54] <Chillum> well I guess we will have to just go on thinking each other is wrong
[15:54] <lopta> I think you're both wrong. <- there, I brought balance to The Force.
[15:54] <Chillum> I have been working with computer security for 15 years and all but whatever
[15:54] * lopta does the Vulcan salute and gets thrown out of the theatre.
[15:55] * elnormous (~elnormous@gateway.evolutiongaming.com) Quit (Ping timeout: 260 seconds)
[15:55] <kerio> and you still haven't understood the point of a csprng?
[15:55] <Chillum> I know exactly what it is
[15:55] * ShanShen (~ShanShen@192.186.126.86) Quit (Quit: [Not usually a quitter, but I quit.])
[15:55] <Chillum> you give it entropy, but it does nto create it
[15:56] <Chillum> I think you are not getting the subtle but crucial difference between random and entropic
[15:56] <lopta> I don't know Linux but I am aware that some other operating systems "save entropy" during a clean shutdown
[15:56] <Chillum> the p stands for pseudo
[15:56] <lopta> Does Linux do that?
[15:56] <kerio> usually, yes
[15:56] <kerio> it's not the kernel, it's userland
[15:56] * arubislander (~ArubIslan@185.107.100.18) has joined #raspberrypi
[15:57] <Chillum> when you reveal csprng numbers created from a certain set of entropy that entropy is potentially compromised by an attacked by observing those csprng numbers. Thus the importance of regularly changing that entropic source
[15:58] <kerio> if the entropy is potentially compromised by an attacker by observing the result you're either generating a LUDICROUS amount of data without reseeding, or the csprng is not actually cryptographically secure
[15:58] <Chillum> that is the assumption
[15:59] <kerio> that is not the assumption
[15:59] <Chillum> that the csprng is insecure, get it?
[15:59] <kerio> no, the assumption is that the csprng is secure
[15:59] <kerio> dear lord
[15:59] * duckpupp1 (~patrickai@h77.131.18.98.dynamic.ip.windstream.net) has joined #raspberrypi
[15:59] <kerio> you don't assume that a critical primitive is insecure
[16:00] <Chillum> you get that security is about assuming that algos can be broken in time right?
[16:00] <Chillum> one of the main features of a hwrng is that the data was created by some physical event that can't just be mathematically broken later, it needed to be observed
[16:01] * Allen_ (~Allen_@c-73-220-153-20.hsd1.ca.comcast.net) has joined #raspberrypi
[16:01] <kerio> what does a hwrng have to do with this
[16:01] <kerio> i'm talking about the fact that the distinction between random and urandom in linux is wrong
[16:01] <Chillum> any source of entropy is about getting data that was not computationally generated
[16:01] <kerio> Chillum: yes, and you shove that data right into the entropy pool of a csprng
[16:01] * Allen_ (~Allen_@c-73-220-153-20.hsd1.ca.comcast.net) Quit (Client Quit)
[16:02] * duckpuppy (~patrickai@66.6.147.81) Quit (Ping timeout: 260 seconds)
[16:03] * cyborg-one (~cyborg-on@62.16.26.194) has joined #raspberrypi
[16:03] <Chillum> again, if you over draw to /random faster than the 20kb/s that the hwrng produces it will silently move over to resusing the entropy
[16:03] <Chillum> you want it to block if you overdraw
[16:03] <Chillum> if your goal is to use the hwrng, you want to always be using it, not just sometimes
[16:04] <Chillum> /urandom that is
[16:04] <kerio> you don't "reuse" the entropy
[16:04] <Chillum> urandom will do exactly that, it will say "ohh no more entropy, I will just keep using the same seed"
[16:04] * lightheaded (~lighthead@242.13.168.213.sta.estpak.ee) has joined #raspberrypi
[16:04] <kerio> it's not like there's a big conditional "if we still have data from hwrng give that data otherwise use a fucking mersenne twister"
[16:05] <Chillum> it simply reseeds itself if it can, and not if it cannot
[16:05] <Chillum> remind me to never use and security based application you designed ;)
[16:06] <Chillum> do you at least agree that /random has higher standards for how it uses its seed data?
[16:06] <kerio> no
[16:06] <kerio> it has a weird counter that estimates "remaining entropy" in a very silly way
[16:07] <kerio> for no reason
[16:07] <Chillum> really? So random will stop and wait for more seed data and urandom will just keep using it, but they do't have different standards?
[16:07] <Chillum> you may not see the value of the entropy pool but it still has value
[16:07] <Chillum> entropy can be a tricky concept to grasp
[16:07] <Chillum> but it is based on sound math
[16:08] <lopta> Do Intel processors ship with a hardware RNG?
[16:08] <Chillum> I am sorry if I have a hard time taking your work for it over decades of security best practices, but you really have not explained why you think it lacks value
[16:08] <kerio> at least modern-ish ones do
[16:08] <Chillum> lopta: I wish mine did
[16:09] <kerio> Chillum: you're the only one insulting me and pulling rank
[16:09] <Shadonovitch> hey, i'm doing A2DP on my bluetooth ; i've had managed to make it output on the analogic, but now everything is played over HDMI, and the command "sudo amixer cset numid=3 1" doesn't redirect to jack
[16:09] <Chillum> not pulling rank, just saying you are contradicting what I know from experience and interaction with very smart people
[16:09] <Shadonovitch> is there a different way to make it play to the jack ? I can't find how i did it earlier
[16:09] <Chillum> you are making an extraordinary claim and I am not hearing extraordinary proof
[16:09] <kerio> i've provided links to posts from what is possibly the best cryptographer in the world and a pretty good cryptographer
[16:10] <kerio> explaining why the behaviour of /dev/random and /dev/urandom on linux is very silly
[16:10] <Chillum> and I am sure many disagree with this learned fellow
[16:11] * lopta disagrees with his own feet.
[16:11] <kerio> yeah like you
[16:11] <Chillum> but I have to disagree with point #2, "we _can_ figure out how to use a single key to safely encrypt many messages " anyone serious about security does not assume PGP or the like will be unbreakable forever
[16:12] <kerio> he said "many"
[16:12] <lopta> Does the Broadcom SoC have an RNG in it?
[16:12] <kerio> not "infinite"
[16:12] <kerio> lopta: the one on the pi? yep
[16:12] <kerio> available as /dev/hwrng, by default
[16:12] <Chillum> this is one of the reaosn perfect forward secrecy rotates keys, but this needs a handshake and won't work for algos like PGP etc
[16:12] <lopta> Well that's nice.
[16:12] <kerio> pgp is not an algorithm
[16:12] <Chillum> with rngs we have the advantage of not having to share key data
[16:13] <Chillum> kerio: I was just using an example he gave
[16:13] <Chillum> but ya, I concede PGP is not an algo
[16:13] <kerio> thanks for the concession
[16:13] <Chillum> well you were right!
[16:13] <kerio> http://www.2uo.de/myths-about-urandom/ this is a decent explanation, if a bit condescending maybe
[16:14] <Chillum> if we could use quantum entanglement to produce the same truly random numbers at the same time for two people then that would be much better than anything we use based on static keys
[16:14] <Chillum> but we certainly would not switch over to csprng when it ran out of bandwidth, not without defeating the purpose of this wonderful device
[16:15] <Chillum> he may be a good cryptographer but his comparison is not really valid in my opinion

[16:19] <lopta> Chillum: I'd say that's true for all software.
[16:20] <lopta> Chillum: ...except Algol60, obviously.
[16:20] <Chillum> yes, which is why hardware rngs don't rely on software but measure physical activity
[16:21] <Chillum> the entropy part is the part not based on math, and thus can probably not be broken by math later

[16:22] <Chillum> I need coffee my brain is running at 60%
[16:22] <Chillum> coffee is my entropy pool
[16:23] <kerio> you keep saying "falling back to the csprng"
[16:23] <lopta> I fetched a fancy coffee from the garage across the road at about 07:55 this morning.
[16:23] <kerio> this tells me that you still haven't understood how /dev/(u)random works

[16:25] <kerio> how's a coffee from a garage better than the coffee in the office

[16:27] <shiftplusone> pi towers went a bit overboard with the coffee. O_o
[16:28] <Chillum> kerio: fine, let me reword it. It falls back to using the same seed it was using before more than it would be budgeted for with dev random

[21:02] <gordonDrogon> ali1234, I've not used it, but I've seen stuff use it. did you initialise it with the right pin mapping - board or bcm ?
[21:02] <ali1234> yes, still doesn't work

[21:02] <ali1234> does wiringPi have python?
[21:02] <gordonDrogon> ali1234, there are some python wrappers on github - but I don't maintain them.
[21:03] <gordonDrogon> https://github.com/wiringpi I think.
[21:03] <ali1234> i have four buttons on four gpios and i want to run commands when they are pushed
[21:03] <ali1234> pretty simple really

[21:03] <methuzla> ali1234: what version pi are you using?
[21:03] <ali1234> what's the simplest way to implement this?
[21:03] <ali1234> methuzla: A+
[21:04] <gordonDrogon> https://projects.drogon.net/raspberry-pi/gpio-examples/tux-crossing/
[21:04] <gordonDrogon> that's just one button, but the principle is there.

[21:06] * oxhak (~OxHaK@unaffiliated/oxhak) Quit (Ping timeout: 256 seconds)
[21:06] <gordonDrogon> you could run 4 shell scripts... one for each button. you'd use the gpio wfi ... command.

[21:08] <methuzla> ali1234: have you tried RPi.GPIO ?
[21:08] <ali1234> methuzla: no, does it have interrupts?
[21:08] <gordonDrogon> you need a Pi with 2 command/terminals in-front if you...
[21:08] <ali1234> i have that
[21:09] <ali1234> gpio -g is broadcom numbers right?
[21:09] <gordonDrogon> di you have anything connected to the gpio?
[21:09] <gordonDrogon> ali1234, yes, -g is bcm numbers.
[21:09] <ali1234> yeah, buttons on 5, 6, 12, and 13
[21:09] <gordonDrogon> are the butons biased - or just gpip pin -> 0v ?
[21:09] <ali1234> i need to activate internal pull up too
[21:09] <gordonDrogon> ok.
[21:09] <ali1234> they are pin -> siwtch -> 10k -> gnd
[21:09] <gordonDrogon> so, do this: in one window: gpio -g mode 5 up ; gpio -g wfi 5
[21:09] * Lorduncan (~Thunderbi@89.7.179.79) has joined #raspberrypi
[21:10] <gordonDrogon> you might need < 10K.
[21:10] * netzfisch (~Thunderbi@x55b06365.dyn.telefonica.de) has joined #raspberrypi
[21:10] <gordonDrogon> the internal is 50K.
[21:10] <ali1234> Usage: gpio wfi pin mode
[21:10] <gordonDrogon> anyway - if you do that, the terminal will hang at the wfi command.
[21:10] <gordonDrogon> sorry - gpio -g wfi 5 falling
[21:10] <ali1234> it works
[21:11] <gordonDrogon> then push the button ... yea.
[21:11] <gordonDrogon> the 2nd terminal was in-case you didn't have the buttons - I was going to get you to set the pull-down resistor to simulate a button push.
[21:12] <ali1234> this is for a headless project
[21:12] * Soaked (~Soaked@unaffiliated/soaked) has joined #raspberrypi
[21:12] <gordonDrogon> and I'm wondering now what RPIO is - I thought you were meaning RPi.GPIO ...
[21:12] <ali1234> i want a button to restart my service if it messes up, and a button to shutdown the pi
[21:12] <ali1234> no RPIO is a python library, all interrupt based
[21:12] <gordonDrogon> well that's how to do it - just run separate shell script for each button.
[21:12] <ali1234> i think it uses RPi.GPIO
[21:12] <methuzla> ali1234: https://sourceforge.net/p/raspberry-gpio-python/wiki/Inputs/
[21:13] <gordonDrogon> hm. ok.
[21:13] <gordonDrogon> good job I don't program in Python :)
[21:13] <ali1234> methuzla: hmm that looks almost identical to RPIO

[21:24] * rigel3 (~rigel3@209.210.157.165) has joined #raspberrypi
[21:25] <ali1234> or apparently it can use RPi.GPIO too
[21:25] <waveform> ali1234, gpiozero polls? Only in the native pin backend which isn't the default

[21:26] <ali1234> and i need to set the pull up resistors too
[21:26] <waveform> under the hood, that'll use edge-detection in RPi.GPIO to detect the button being pushed
[21:27] <ali1234> i'll read the docs :)
[21:27] <waveform> nope - the fact it knows it's a button means it'll set pull-up for you
[21:27] * rigel3 (~rigel3@209.210.157.165) Quit (Client Quit)
[21:27] <ali1234> but how does it know if i want pull up or pull down?
[21:28] <waveform> it defaults to up (but you can specify down). We assumed up as the default because then the circuit connects to ground, same as the basic LED circuit

[21:29] <ali1234> um... where is the documentation?
[21:30] <ali1234> it just links to itself...

[21:35] <ali1234> instead of saying button.when_pressed=<a function>
[21:35] <ali1234> can i just override when_pressed?
[21:35] <waveform> well, when_pressed is a property rather than a method so overriding it is not quite trivial
[21:35] <ali1234> oh :(
[21:35] <waveform> but, it is possible to override a method to be called on activation - let me dig out which it is

[21:38] <waveform> heh - there's meta-classes at the base of gpiozero - it's easy at the top and gets progressively nastier the further you go down
[21:38] <waveform> ah, there it is: _fire_activated(self) is the method that gets executed when the device is activated (which in turn kicks off when_activated, when_pressed, etc.)
[21:39] * duckpuppy (~patrickai@66.6.147.81) Quit (Ping timeout: 264 seconds)
[21:39] <ali1234> what about when_held?

[21:39] <waveform> nope - that one's trickier - there's a background that periodically fires that off (in another mixin) - just a sec
[21:40] <waveform> (because when_held isn't fired by anything electrical)

[21:54] <waveform> (sorry about that - should work out of the box)
[21:55] <Simonious> anyone used nilfs2 with raspian?
[21:55] <ali1234> with bounce_time=1 the actual delay is about 5 seconds between presses
[21:55] <ali1234> but... hmm i did say yesterda that the whole system feels slow, like a clock is wrong
[21:56] <ali1234> with bounce_time=None there's no delay... but there's bounces
[21:56] * humbot (~i@unaffiliated/humbag) has joined #raspberrypi
[21:56] <waveform> ali1234, yeah - I'd leave off bounce elimination for now - I'm not convinced RPi.GPIO does it terribly well
[21:57] <waveform> (gpiozero just passes all that stuff down to the pin driver so we rely on its implementation - it's one of the reasons we're moving toward pigpio as the default backend)
[21:57] <ali1234> i need debouncing though
[21:57] <ali1234> it seems to work fine, just seems confused about the length of a second
[21:58] <waveform> well, you can try pigpio as the backend and see if that improves things
[21:58] <ali1234> how?
[21:58] <enginerd123> my RPi storage got filled, and now will no longer boot...it shows the Raspian logo, then goes black with a blinking cursor. Any suggestions?
[21:58] <waveform> first enable pigpio's daemon: systemctl enable pigpiod
[21:58] <waveform> then run your script with GPIOZERO_PIN_FACTORY=PiGPIOPin in the environment
[21:59] <ali1234> this is an A+
[21:59] <Simonious> enginerd123: can you make an image of that sdcard and then write it to a new bigger sdcard?
[21:59] <ali1234> i'm more and more suspecting a clock is messed up
[21:59] <waveform> (warning: this is experimental stuff and that variable *will* change in the next release)
[21:59] <enginerd123> I tried, but every time I do that, it partitions the bigger card (16gb) down to 2gb
[21:59] <Simonious> enginerd123: or.. *thinks* put a clean install on a bigger card and then pull over the things you need from the old install
[22:00] <Simonious> enginerd123: yes, but does it boot?
[22:00] <enginerd123> no
[22:00] <enginerd123> same problem
[22:00] <Jusii> you need to resize the partitions after clone
[22:00] <Jusii> fdisk + resize2fs
[22:00] * Simonious nods
[22:00] <waveform> ali1234, not so sure about the clock being messed up - I've had the same debounce issues with RPi.GPIO on a Pi3 (not quite as extreme as a full second, but it's way more than specified)
[22:00] <ali1234> this should be 1 second but its more like 5-7 seconds
[22:00] <enginerd123> is it possible a lack of disk space is causing the boot issue? It ran out when I tried to install sympy
[22:01] <ali1234> enginerd123: yes

[22:04] <Simonious> If you can mount it on another machine you can copy it to a USB stick that you can use on the pi OR just transfer them via network.

[22:05] <ali1234> can i specify a float for debounce time?
[22:05] <waveform> sure

[22:13] <waveform> ali1234, hmmm - just a mo and I'll rig up a button to test
[22:14] <ali1234> i'll put a scope on it, make sure it's not my wiring
[22:14] <icee> ps -eFL correctly shows oodles of lightweight processes.. but gdb just shows the one.
[22:14] <waveform> ali1234, can't seem to reproduce missing the first one - fires nicely for me
[22:14] <HoloIRCUser> Hello guys I need a media center computer, like watching on streaming football games in HD. I was thinking to buy a cheap laptop, but then I thought 'Ehy the raspberry pi is just 30€!'. Do u think the raspberry pi 3 could do the job?
[22:15] <ali1234> maybe related to the suspected messed up clock
[22:15] <waveform> 'course might not be the "first" pulse if my switch is bouncy
[22:15] <ali1234> any idea how i can check that?
[22:15] <waveform> oh, and I am testing on a Pi3 here - the A+ is buried somewhere :)
[22:15] <ali1234> i'm using tactile switches... they are not very bouncy
[22:15] <kerio> HoloIRCUser: might get away with a pi0w actually
[22:15] <kerio> 10 monies
[22:16] <kerio> ...honestly tho, just buy a chromecast

[22:16] <Simonious> enginerd123: Hmm, well I can't mount it on the windows box I am on.. that's not true I can mount it, but linux doesn't know how to read it. I *think* on a linux box you could mount the image AND read it
[22:16] <kerio> HoloIRCUser: it probably is
[22:17] <kerio> it's not going to be as simple of an experience as a chromecast tho
[22:17] <kerio> keep that in mind
[22:17] <methuzla> HoloIRCUser: if the software engages the GPU, any pi can handle it
[22:17] <kerio> if your streaming site is supported by youtube-dl or livestreamer, then it's going to be easy

[22:18] <HoloIRCUser> methuzla: that sounds great
[22:18] <kerio> the pi 0 is tiny ;o
[22:18] <kerio> buy one
[22:19] <waveform> ali1234, oh there's something interesting ... https://sourceforge.net/p/raspberry-gpio-python/code/ci/default/tree/source/event_gpio.c#l324 <-- that's the chunk of RPi.GPIO that handles edge detection
[22:19] <kerio> everyone needs to buy one
[22:19] <HoloIRCUser> kerio: ahah ah I will some day
[22:19] <waveform> ali1234, note the "ignore first epoll trigger" line ... there's probably a good reason for that (which I don't know off the top of my head) but I wonder ...
[22:20] <kerio> unless you have ethernet behind your tv, 0 and 3 shouldn't really make much of a difference
[22:20] <kerio> the heavy lifting is done by the gpu core
[22:20] <ali1234> waveform: i did implement the polling loop myself once, it was annoying
[22:21] <enginerd123> hmm, Simonious is it normal for the image partition to naturally only be 2gb, then it uses the remaining 6gb on an 8gb disk as file storage? Or should the image show 2gb of 8gb used for the image partition?
[22:21] * mmazing (~mmazing@unaffiliated/mmazing) has joined #raspberrypi
[22:21] <waveform> epoll ultimately does the heavy lifting in RPi.GPIO (edge detection is effectively epoll on the sysfs files). In native I used the GPIO registers to do edge detection instead, but that turned out to have drawbacks of its own
[22:22] <HoloIRCUser> I actually thought about a raspberry pi 3 because it's not for me, it would be for a public place in which we steam football games. So if raspberry does support HD playback, I'd install q4os on it with Xp skin package, so it will look extremely close to windows and make it be easy to be used by anyone. It'd be connected to a projector and on the net through an Ethernet cable
[22:22] <Simonious> enginerd123: I don't know what is normal. ;) So much variation out there. When I install a 2GB image on a larger card I go into raspi-config and find the 'expand filesystem' option to use all the space
[22:22] <Simonious> I do also mount a USB stick to /home
[22:22] <HoloIRCUser> We'd just need to spend 2€ for a keyboard and a mouse and then boom we have a computer with 32€ instead of 300
[22:22] <kerio> HoloIRCUser: yeah no
[22:22] <Simonious> because that is where I do datalogging and I don't ant to murder my sdcard
[22:23] <HoloIRCUser> kerio: why no :(
[22:23] <HoloIRCUser> kerio: you are breaking my dreams :(:(
[22:23] <kerio> because you're not going to be able to just open chromium and go to your streaming site and play the video back
[22:23] <Simonious> I've got nilfs2 on there right now and it is giving me a little trouble, I've not nilfs-tools installed, but it isn't auto running cleanerd like it does on ubuntu, so I need to get that setup as a service

[22:28] <Simonious> enginerd123: yeah give that a go
[22:28] <methuzla> HoloIRCUser: the stream will most likely be some form of compressed video, which will need to be decompressed on the pi
[22:28] <Simonious> you may find that image can be mounted when it doesn't have to do the booting.

[22:41] <waveform> yes - which means it's something in epoll or sysfs (or some interaction between them - urgh)
[22:41] <ali1234> i set bounce to 0.01 and its not dropping the first event now
[22:43] <waveform> I expect it's still suppressing more edges than it should though?
[22:43] <ali1234> maybe. it looses a press every now and then
[22:43] <waveform> yeah - that's usually my experience of it
[22:43] <ali1234> seems like a subsequent "bounce" can mask an edge that already happened
[22:44] <ali1234> if timeout is 1 and you press really fast, you can prevent the event from ever firing
[22:44] <ali1234> until you stop anyway
[22:44] <waveform> indeed - which just shouldn't happen
[22:45] <waveform> unfortunately I haven't got time to dig into it further right now, but when I get onto gpiozero work later this week I'll try and remember to have a poke around that stuff
[22:47] <ali1234> any advice for how to debounce manually in python?
[22:47] <methuzla> time.sleep()?
[22:47] <ali1234> well, will that just queue up the events?
[22:47] <SpeedEvil> ali1234: 100ms post last change, after 10 samples, for example
[22:47] <SpeedEvil> sample every 10ms
[22:48] <ali1234> i am using gpiozero
[22:48] <ali1234> it is interrupt driven
[22:48] <methuzla> oh yeah.
[22:48] <SpeedEvil> Then add a timer to check if the last change was 10ms ago
[22:48] <ali1234> yeah
[22:48] <SpeedEvil> 100
[22:48] <ali1234> i'll just reimplement the same logic

[23:27] <methuzla> enginerd123: i'd guess it's like gordonDrogon said. four different partitions. maybe just mount them all and see which one has what you want.
[23:27] <leftyfb> spoutnik16: you won't get help with that here
[23:27] <spoutnik16> that's just theoretical
[23:27] <leftyfb> spoutnik16: right. Good luck
[23:28] <methuzla> spoutnik16: the same way you'd do it with your own network
[23:28] <spoutnik16> ok, next question: is it a bad question to ask where i should get such an answer ?
[23:28] <leftyfb> spoutnik16: google
[23:28] <spoutnik16> google is not a place, google is the internet :)
[23:29] <spoutnik16> next question :) : i would like to have a raspberry pi i could let at home and use as a vpn, how do i do that ?
[23:29] <leftyfb> spoutnik16: http://bfy.tw/AlyD
[23:29] <leftyfb> there ya go
[23:29] <Broly> NetWinder Floating Point Emulator V0.97 (extended precision) http://pastebin.com/arNzC82d is this emulation a result of the wlan "blobs" being softfloat? i know this is the reason it panics after startup (can't initialise them). just found the emulator bit curious because when it checks the procs it detects VFP mode (just can't use it, again i suspect due to the blob)
[23:29] <spoutnik16> leftyfb: thx :)
[23:29] <Broly> ^ none of you guys can answer this question that's not the purpose of me sharing the above
[23:30] <enginerd123> ok I have the usb mounted, how can I unwrap the image so I can recover files?
[23:30] <Broly> it's more to convey there are some seriuos questions regarding the hardfloat "feature" on armv7 and up, especially when you're only linking wlan blobs. no reason the kernel built for the architecture should flip on an emulator. i'm pretty sure it's on the broadcom end
[23:30] <spoutnik16> leftyfb: *steal* was the magic keyword i was looking for, thank you
[23:30] <Broly> ARM is in serious trouble. no wonder rothschild booked it out in late 2015
[23:30] <Broly> freakin' runt
[23:31] <Broly> shouldn't need an emulator for a hardfloat CPU when the kernel is being built from *SCRATCH*
[23:31] <Broly> as you can see the VFP feature is picked up without issue (again, just can't use it)
[23:32] <spoutnik16> !!! i saw a guy use a raspberry pi in Mr Robot, this must be such a cool hype hacker tool !!!

[23:37] <ExeciN> I'm trying to bring xdebug in my php7 environment. I fetched php7 from the stretch raspbian repo so when I try to install php7.0-dev from stretch it tries to fetch the rest of the stretch repo too
[23:38] <Broly> clever: not drivers. programs that i want to compile in the OS
[23:38] <leftyfb> no, it tried to pull in the php7.0-dev dependency tree

[23:39] <clever> Broly: if hardfloat is available, it shouldnt need fpu emulation, x86 works the same way
[23:39] <Broly> it does though
[23:39] <clever> weird
[23:39] <Broly> as you can see in the boot log posted above, it detects VFP but flips on teh emulator
[23:39] <Broly> not weird, it's a fraud
[23:39] <ExeciN> well, I like to exaggerate
[23:40] <Broly> i checked the dd-wrt kernel that's softfloat and it does not call the emulator
[23:40] <Broly> so this issue is strictly when you build a proper hardfloat ARM kernel for the target
[23:40] <ExeciN> is there any other way to get xdebug without fetching the whole stretch repo?
[23:40] <leftyfb> ExeciN: every one of those is part of the dependency tree for the package you're trying to instal

[23:40] <leftyfb> ExeciN: it's not the whole stretch repo
[23:41] <leftyfb> ExeciN: and no, unless you don't want it to work
[23:41] <leftyfb> ExeciN: that's why they're called dependencies
[23:41] <ExeciN> I know, its just a lot of packages (and I like to exaggerate)
[23:41] <leftyfb> it's 33 new packages
[23:41] <leftyfb> 46mb
[23:41] <leftyfb> that's nothing
[23:41] <ExeciN> yeah I'm more worried about the "375 not upgraded" part
[23:42] <leftyfb> why?
[23:42] <leftyfb> actually, looking at the list, upgrading things like libc6 and not the rest of your OS might be problematic
[23:42] <ExeciN> because if I upgrade I'm gonna find my pi installing 375 packages
[23:42] <leftyfb> don't upgrade
[23:43] <ExeciN> if I don't use -t stretch nothing needs upgrading
[23:43] <leftyfb> install what you need from the repo and then disable it
[23:43] <ali1234> ExeciN: http://jaqque.sbih.org/kplug/apt-pinning.html
[23:43] <leftyfb> heh
[23:44] <leftyfb> ali1234: are you suggesting he pins 375+ packages? :)
[23:44] <ali1234> no, it doesn't work like that
[23:44] <ExeciN> ali1234: I thought about pinning but I'm worried that they packages will get stuck
[23:44] <ali1234> you set stretch priority lower, and then pin what you want from stretch

[23:49] <badger_> is there a way to turn off red and green leed on RPi3? after looking for a solution I concluded it's not possible :( am I wrong? I hate to not be able to turn off lights in a non-physical way

[23:53] <Broly> it does not support a built from scratch kernel out of the box, as you have to link broadcom's blob to make it boot
[23:53] <Broly> but there is a blob available, so it's semi outta da bawx
